TO WHOM IT MAY CONCERN:V

Ifnow all men that I, CHARLES MUDGE, of Ovid, in the county of Clinton,and State of Michigan, have invented a new and useful Improvement in Builders and PaintersA Saalfeld; and I do declare that the following is a true and accurate description thereof, reference beingihad to the accompanyingr drawings, andt'o the letters of reference marked thereon, and being a part of this specification, i y

IThe object of this invention is te construct an apparatus for-sustaining and adjusting platforms, for the use oi' builders and painters, that will save the expense of ladders, will furnish amuch 4safer platform than those in ordinary use, and will be easily transported and set upfor use. i i

A is the sido of a building, and B the reef. C are plates, the upper ends of which are wedge-shaped, which v allows their points to4 be' forced under the ends of the shingles, and are provided with two openings, E, to receive the hars M, as hereinafter described. To the plates C are attached theadjustable spurs D, which-are designed to holdthe plates firmly in place, by forcing the points of the spurs into the shingles. These plates C are cach provided with two openings, one ahove the other. Thescopenings E are for the purpose ot'holding the bars "di, which are l,plaeedin the upper or'loweropepings, as' circumstances may require, teiclear eaves-troughs, or other projections on the roof.

l are vihrating-latches, provided with proper springs, pivoted tothe plates 0, and are intended to catch into the depressions'or racks 7, in the hars M, to prevent their sliding downward, but, at'the same-time, will admit of the hars being moved up er down, as circumstances may require. At-thei`r upper ends are hinged supporting-bars N, hinged at their other ends to braees,.Z, which braces serve to sustanand holdthe bars hh at' any desired angle, by securing the lower ends oi' the braces in notches, 2, in the bars M; the whole togetherw forming avery convenient and elheient scaii'old for shingling purposes. l A

At the lowerends of the bars M are securely fastened the plates F, which project far enough over the ends of said bars to form an leyein the plates, forthe insertion of proper hooks, which forni a part ofthe plates J, which are attached lto the standards G, 'to which vtho following-described parts of the apparatus are attached: At each end of the standards G, and upon thc inner sides thereof, are secured, within proper boxes O, the pulleys '.l, which are connected in pairs bythe ropes R, and all keptin parallel motion by the-square rod K, which passes through thelowcr pulleys. e

p L are braces passing"through slides U, and 'securcd'in place by proper pins through the braces, and resting against the hack side of the standards Gr, the-forked ends of said braces-resting againstthe building, thetfl securing a vertieal'and parallel position of lsaid standards. y n i H are sliding adjustable platformeupporters, which are secured loosely to the standards Gr, by the straps Vv passing laround said standards, while their ends are securely fastened to the supporters'H,whichare supported by pawls, X,which are fitted to thc'lowcr ends ofthe supporters H. Y. The upper-ends of said pawls X are hinged to the supporters II, and between the lower ends of the pawls and .the supporters are placed ysuitable springs, which press against thc lower ends of said pawls, and secure their catching in thenotches 3, in the standards G,

A thereby supporting the platform-supporters Il.

The lines or cords Q are connected, at their lower ends, with the lower ends of the p awls. By pulling said .ropes, (which can he donc by any one standing upon the platform,) the pawl is drawn back, wlxielireleases the same from the notches, and allows the supporters to slide up and down freely.

The ropes ll. are fastened to the supporters 1I by proper fastcnings, S, by which arrangement the platform, which is made by placing plank upon the arms of the supporters H, may be raised or lowered by the operator without leaving the platform, by iirst releasing the pawl's, as hcreinbeforc described, and allowing the whole to slide down, regulating the motion by grasping with the hand' the hach-rope R, elevating or depressing the platform, as may he desired, as with ordinary ropes and blocks.

The hooleplates dare so arrangcdvthat thcyarc adjustable upon the standards G, allowing them tl'lic' changed up or down', according to the height of the building.

The standards G m cvcr desired.

What I claim as my invention, und desire to secure by Letters Patent, is

1. The slide-bars M, the supports N, standard-braces Z, the plz-tes C, provided with slots Espurliooks J), the vib'nting-rods and springs P, when airangednnd operating in connection with hnngcwphites F.

2. The `standards G, the plntformssnpporters H, projections 3, paw] or clip X, operated by ropes 'R and Q, pulleys T, and rod K, when constrcte'dand operating sbstantialiy as and for the purposes set forth.

3. The combination ofthe foregoingnalned parts with the adjustable 1;ookpiates I und braces L, arranged', constructed, and operating substantially as herein shown and described.

oy be used uponl ends of-imildings, .and secured to thc'rroof by plate and spurs Y, when- WMM CIIAS. MUDG'E.
